Ninety-nine percent of these also contain six neutrons.The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.90% of the time, speakers of English use just 7,500 words in speech and writing.
All carbon atoms have a nucleus containing six protons.How Carbon Dating works Carbon dating is one method scientists use to measure the ages of objects which were alive at some time in the past. In our atmosphere there are particles of carbon, when rays from the sun hit them it turns a few of them into carbon 14 (a radioactive carbon). One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites. Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.
